A little help, please? :)

привет!

I hope everyone is enjoying their summer (I realize, it's not summer everywhere... so I guess also what would it be? Winter season?) Anyways! I hope everyone is enjoying their month of August (there, that solves it).

I have a quick favour to ask! I've been trying to construct a sentence and hopefully it makes sense and if not... well.. that's why I'm asking for your help! :)

So... I want my sentence to somewhat say this..

Thank you for everything.

We would like to invite you to breakfast, lunch or dinner (whichever is more convenient.) Or maybe even just tea?

Best of luck on your upcoming project!

Now, I think it should be something like...

Спасибо за все!

Мы хотели бы пригласить тебя на завтрак, обед или ужин (что является более удобным.) Или даже просто чай?

For "best of luck on your upcoming project" I have absolutely no idea just because "best of luck" seems like a saying... therefore, I don't really know if it's translatable. Maybe it is, and I'm just overanalyzing.

Any help would be greatly appreciated!

спасибо!
